How do if-conditions work?

[SuziQ-407]

Hi listmonkers,

I only found ONE example of an if-condition in the docs (Templating). So I have to try for myself how listmonks if-conditions works. My current example:

At the end of a personal mail I want to write:

• "Greetings." --> if current subscriber has an empty attribute {{.Subscrier.Attribs.city}}
• "Greetings to London." --> if subscriber already has a value ("London") in this attribute.

So I tried following (similar to the example in the docs):

{{ if eq .Subscriber.Attribs.city "" }}
Greetings.
{{ else }}
Greetings to {{ .Suscriber.Attribs.city }}
{{ end }}

But on previewing I got the error "{template: content:7:123: executing "content" at \u003c.Suscriber.Attribs.city\u003e: can't evaluate field Suscriber in type *manager.CampaignMessage"}".

I have discovered that if I remove the second "{{ .Suscriber.Attribs.city }}", there is no error.
I note that only text, but no variables, can be output in if-conditions. If this is right, I find it very poor.

So I guess that nested if-conditions are impossible ...

Has anyone experience with if-conditions yet?

Greetings {{to all}} ;-)
